Spektr-R | Decommissioned, single array, 10 meter diameter
From your link: "The very high angular resolving power was achieved in conjunction with a ground-based system of radio-telescopes and interferometrical methods, "
HALCA | Decommissioned, single array, 8 meter diameter
From your link: This orbit allowed imaging of celestial radio sources by the satellite in conjunction with an array of ground-based radio telescopes" … “the project was eventually cancelled in 2011 due to increasing costs and the difficulties of achieving its science goals”
Orion | “It is believed that this refers to the diameter of the main antenna, which might be well in excess of 100 m”, potentially you’re correct! Oh. These are ground facing dishes that aren’t use for scientific purposes and are highly classified.
Your point? You said it wasn’t feasible to do this in space, yet they already are and have larger sizes than on earth…. Also they’ve been doing this for decades and already decommissioned stuff and you claimed it was never done…? The hell…?
Your own earth based one you linked has even buddied with them as you so nicely quoted… so which is it? It’s not possible? Never been done? And you were making fun of MY comment? Lmfao.
